Identification of the Cow-Fly — Hsematobia serrata. (Country Gentle- 

 man, for November 29, 1888, liii, p. 893, c. 2-3 — 20 cm.) 



The fly, which has been the subject of former communications in the 

 Country Gentleman and which Dr. Williston purposed soon to describe 

 as Stomoxys cornicola, has been determined by Baron Osten Sacken, of 

 Germany, to be identical with Hcematobia serrata of B. Desv., of South- 

 ern France and Italy. Other generic references of the fly are given. 



[See notice of this insect on pp. 220-227 of this Report.] 



Wire-Worms. (Country Gentleman, for November 29, 1888, liii, 

 p. 893, figs. 1-6, c. 3-4 — 51 cm.) 



To an inquiry from Potter county, Pa., for means of relief from exces- 

 sive injuries from wire- worms, three of the best remedies are named and 

 remarked upon at some length, viz., starvation, a crop of buckwheat, 

 and a crop of mustard. As a guard against mistakes often made, the 

 difference between wire-worms, cut-worms, and thousand-legged worms 

 are pointed out and illustrated by figures. 



Egg Deposits of Flower Cricket. (Country Gentleman, for December 

 6, 1888, liii, p. 911, c. 1 — 24 cm.) 



Grapevine from Eaglesville, O., show egg-deposits on leaves 

 (described) which have hitherto been referred to the white-flower cricket, 

 (Ecanthus niveus Harris ; but there are reasons for believing them to 

 be those of (E.fasciatus DeGeer — a valid species, and not a variety of 

 niveus. The remedy for the attack is cutting off and burning. Food- 

 habits of the insect stated. 



The grape leaf eating beetle of which inquiry is made, is Pelidnota 

 punctata (Linn.) — remarks upon it. 



White-Marked Tussock Egg-Clusters. (Country Gentleman, for 

 December 6, 1888, liii, p. 911, c. 1-2 — 16 cm.) 



The eggs on cocoons sent for name from Salem, N. J., are those of 

 Orgyia leucostigma (Sm.-Abb.). The insect is pernicious. Its egg- 

 bearing cocoons (these only) should be destroyed, and where they may 

 be looked for. One of the cocoons gave out a parasite, Pimpla 

 conquisitor Say.
